In Bibliographic field 043 (Geographic Area Code) and all OCLC-MARC Authority field 043 (Geographic Area Code) rule sets, all codes in subfield $a (Geographic Area Code) are validated against the MARC Code List for Geographic Areas, regardless of the presence of subfield $2 (Source of Local Code). Codes in subfield $b (Local GAC Code) are not validated because they are locally assigned. The existing relationship between the presence of subfield $b and the presence of subfield $2 remains in place.
